I’m having an issue in firing the uploader.start() in case if start button is not clicked for file upload, I am using latest version Plupload. here is the complete code, and I want to find the temp names given for each file uploaded on submit click, so that I can go to the server and rename the files with the reference ID which makes easy to identify the file that belongs.

     <html xmlns="http://www.w3.org/1999/xhtml">
    <head runat="server">
    <link href="Styles/jquery.plupload.queue.css" rel="stylesheet" type="text/css" />

    <script type="text/javascript">
        $(document).ready(function () { 
          $("#Testloader").pluploadQueue({
              runtimes: 'flash',
              url: 'FileUpload.ashx',
              max_file_size: '100mb',

              //unique_names: false,

              filters: [

            { title: "Image files", extensions: "jpg,png" }
        ],

                      plupload.each(files, function (file) {

                      });
                  }
              }

          });
      });
      $('form').submit(function (e) {
          alert("clicked me");
          var uploader = $("#Testloader").pluploadQueue();
          // Files in queue upload them first
          if (uploader.files.length > 0) {
              // When all files are uploaded submit form
              uploader.bind('StateChanged', function () {
                  if (uploader.files.length === (uploader.total.uploaded + uploader.total.failed)) {

    First, you should move the submit binding inside the $(document).ready to ensure the DOM is ready for submit binding.

    I guess you should try relying on a closure to ensure “uploader” is correctly bound during StateChanged (you could also begin your StateChanged Handler with var uploader = $(“#Testloader”).pluploadQueue();) :

      $('form').submit(function (e) {
      alert("clicked me");
      var uploader = $("#Testloader").pluploadQueue();
      // Files in queue upload them first
      if (uploader.files.length > 0) {
          // When all files are uploaded submit form
          uploader.bind('StateChanged', (function(closedUploader){return function () {
              if (closedUploader.files.length === (closedUploader.total.uploaded + closedUploader.total.failed)) {
                  // $('form')[0].submit();
                  alert("Form submitted");
              }
          };})(uploader)
          );
          uploader.start();

      } else {

          alert('You must queue at least one file.');

      }
      return false;
  });

    Hope this will help
